There are multiple reports claiming Odell told opposing players and coaches to "come get me" out of Cleveland ... essentially letting people know he's unhappy with the Browns and wants to get out.

Of course, Beckham didn't choose to play for Cleveland in the first place -- he was traded there by the Giants earlier this year.

Additionally, Beckham expressed frustrations with the Browns training staff -- suggesting they did not properly handle the sports hernia injury he suffered in training camp.

But, Landy -- who's been super tight with Beckham since high school -- came out strong to reporters today, saying the superstar WR is not trying to jump ship.

"He doesn't want to leave and he's not trying to leave," Landry said moments ago.

"It's not even about trying to go somewhere else," Landry added ... noting that Beckham's been a solid teammate and consummate pro during his run in Cleveland.

For his part, Odell has tweeted about the reports saying, "I NEVER said I was not happy in Cleveland, just like everyone else I’m hopeful for better results. Period. Next story plzz."
